The y-intercept of ƒ(x) is indicated by the red dot at (x=0, y=1). In analytic
geometry, using the common convention that the horizontal axis represents a ...
Because functions associate x values to no more than one y value as part of their
...

When you find where the x-intercept is located, the y-value is zero! ... To find the x
-intercept, you solve the equation using y = 0. To find .... equation; a value of x
that makes a function f(x) equal to 0, a zero of a function may be real or imaginary
